ACETYLENE-GAS-G EN ERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 726,139, dated April 21, 1903,

Application filed June 10, 1901. Serial No. 63,965. (No model.)

To all whom, it may concern.-

Be it known that I, CHARLES BUsoH, technologist, a citizen of the Republic of France, residing at 8 Rue Thimonnier, Paris,in the Bepublic of France, have invented certain new and useful Improvements in Apparatus for Generating Acetylene Gas, of which the following is a specification.

My invention relates to improvements in acetylene-gas-generating apparatus and in carbid-cartridges therefor; and it consists in the construction of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a sectional view of an acetylene-gas-generatinglampembodyingmyimprovements. Figs. 2, 3, 4, and 5 are detail bottom plan views of various modifications of the carbid-cartridge.

The font or outer vessel e, adapted to contain water, is open at its upper end. In this vessel is placed a bell c, the cover 7?. of which also forms a closure for the upper end of the vessel e and is detachable therefrom, so that the bell may be readily removed from said vessel. A gas-conduit leads upwardly from the said cover, is provided with one or more suitable burner-tips, (two being shown in the present instance,) and is further provided with a cock at. The cover it also has an airvent cock m. Within the bell, the lower end of which is submerged in the body of water in the vessel 6, are carbid-cartridgesupporting spring-arms (1, preferably of the form shown.

The carbid-cartridge a is of cylindrical form, contains a suitable quantity of carbid, is hermetically closed, as by soldering or otherwise when charged, and is provided in the bottom only with minute openings 1?, which in practice are about as fine as hairs. Prior to the insertion of .the cartridge in the bell these openings also are closed, as by a paper or other label pasted on the bottom of the cartridge A, the paste used being soluble in water. It will be observed by reference to Fig. 1 of the drawings that when the bell is in place in the vessel ethe'lower portion of the carbid-cartridge is submerged, thereby causing the label to become loosened and to drop off and permitting the water to enter the cartridge through the minute'openings b. and attack the carbid,- the level of the water in the bell being indicated at ff.

The gas produced in the cartridge (1, not finding an issue upwardly, is obliged to pass downwardly through the carbid and to make its exit through the same openingsb through which the water entered. At the same time the gas drives back the water which has entered the cartridge. The gas is quite cold, because the cartridge is at all times either partially or entirely submerged. The gas is never given off tumultuously, because the quantity of water coming in contact with the carbid isextremely small and the water is immediately thereafter emptied from the cartridge by the pressure of the gas.

Afterissuing from the apertures b the gas is forced upwardly through the water in the lower portion of the bell. It is thus purified, first by circulating'through the carbid, then by making its exit through the apertures b, which cleanit mechanically, and, lastly, by passing through the water. The apertures 12 can never become obstructed during the operation of the lamp,because it has been foundthat owing to the minute size of the openings and the variations of the alternate gas and water pressures solid particles cannot adhere in said openings.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation. Various changes in the form, proportion, and the minordetails of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, I claim 1. A carbid-cartridge hermetically closed and provided in'the bottom only with minute openings for the entrance of water and the escape of gas. V

2. In combination with acetylene-gas-gencrating apparatus including a water vessel and a bell,a carbid-cartridge in the bell,adapted to be submerged, hermetically closed, and provided in the bottom only with minute openings for the entrance of water and the escape of gas.

Intestimony that I claimthe' foregoing as my invention I have signedmy-na'me in presence of two subscribingwitnesses.
